Welding High Penetration Speed (HPS) Process in synergic mode
Table 12 Exemplify synergic programs for HPS
Wire material
Steel
Note: The list of available programs depends on the power source.
In synergic mode, the welding voltage is not set directly
by user.The correct welding voltage will be set by the
machine's software.
Optimal voltage value is related to the input data:

Wire Feed Speed, WFS.
HPS is a modified welding process designed by Lincoln
Electric that combines the advantages of the spray and
short arc modes.
Lower welding voltage than in the classic spray arc mode
cause lower energy and more concentrated arc.
Advantages:

The possibility of welding with long stick out.

Concentrated arc that increases penetration.

Reduction of workpiece distortion (lower voltage =
input less energy into the weld).

Increased productivity (higher welding speed and
reduced requirements for preparing the material for
welding).
If it is needed, the welding voltage can be adjusted by
the right control [23]. When the right control is rotated,
the right display [20] will show a positive or negative bar
indication if the voltage is above or below the optimal
voltage.

Pinch controls the arc characteristics during short-arc
welding. Increasing Pinch Control results in a crisper arc
(more spatter) while decreasing provides a softer arc
(less spatter).

Adjust range: from -10 to +10.
